Claims

[Claims for Utility Model Registration] 1. An arc-extinguishing chamber having at least a pair of contacts that open and close, and an arc-extinguishing plate in which a notch is formed opposite to the pair of contacts, the arc-extinguishing plate A switch made by forming a thin part on the plate. 2. The switch according to claim 1, wherein the arc-extinguishing plate is formed in a tapered shape so that the end portions on the side of the pair of contacts are tapered to form a thin portion. 3. Place the arc-extinguishing plate around the notch or the thinner part of the plate.
The switch according to claim 1 of the utility model registration claim, which is formed in a stepped shape so that the switch has a stepped shape.
